ABOUT THE TEAM
The Data Team at Unzer is responsible for the end-to-end health and evolution of our data platform. We build and operate a multi-repository, distributed stack spanning orchestration, transformation, lake ingestion, and infrastructure configuration. Our processing patterns range from batch to near real-time, with a strong emphasis on availability, data quality, and operational robustness in a 24/7 production environment. We like having the freedom to pick the right tooling and approach for each use case, and our goal is to make data easy to access and understand across the company, so people can actually make decisions based on it.
What your work will look like:
- Own data pipelines end to end: design, build, run, monitor, and troubleshoot across orchestration, transformation, lake ingestion, and cloud infrastructure.
- Build and maintain Apache Airflow workflows to schedule transformation jobs, ingestion tasks, and containerized workloads.
- Develop dbt models in Redshift (or a similar warehouse), including incremental strategies, data quality tests, and CI validation, and coordinate model selection and run parameters with orchestration.
- Design and build lake-layer pipelines (bronze, silver, gold, or your platform's equivalent), including replication, ETL/ELT jobs, and operational workloads for event-driven and near real-time use cases.
- Implement workloads as containerized services or serverless functions depending on what fits best, and manage batch jobs, platform monitoring workflows, and container image lifecycle.
- Manage cloud infrastructure and configuration: compute clusters, object storage, IAM, the data warehouse, networking, parameter stores, secrets, and access and grant management.
- Maintain CI/CD pipelines (for example, GitHub Actions) with secure cloud authentication, and own the flow from test to production.
- Investigate and resolve production incidents, including orchestration failures, transformation run issues, serverless errors, replication lag, performance bottlenecks, and data quality problems, using monitoring and alerting effectively.
- Follow the typical new source flow end to end: configure replication or ingestion, land the data in object storage, build the consumer or transformation layer, wire up the compute, orchestrate it, model it in the warehouse, and grant access.
What you need to be successful in this role:
Nice to have:
- Infrastructure as Code (Terraform, CloudFormation).
- Event-driven architecture (Kafka or similar).
- Additional languages used in ingestion or operational repos, such as Go.
- Financial services or payments data pipelines experience.
- Search or indexing experience, Avro, or schema registries.
Please note that we will not sponsor your visa or relocation, and you must have a valid work permit to be eligible for this position.
